What is a safe level to over clock?

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance
Cheers

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?

Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic

IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.

I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again
Cheers
Corey
Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?

I go to 1.6 but use the Trinity App to go back to stock when OC not needed

I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.

60C too hot? Nexus 7

Hey guys I have my nexus 7 OC to 1.6ghz? MIN and MAX. It runs on 60C is that too hot? I'm using motley's kernel 520mhz GPU ?

its a little warm, but normal for 1.6ghz if youre using the device.

What is considered too hot? 70C ? I do have a gaming PC and do the same rules apply to what is considered too hot? For me 80C is too hot for my GPU on my PC. Is it fine to have the same mindset when it comes to my N7?

stock thermal throttle is 85C(some custom kernels set this higher or lower). at that point the device will lower the cpu speed to cool itself off. safety shutdown is at 100C. if at 1.6ghz, and gaming, its probably normal to go into the 70C's if its a cpu intensive game. it also depends on the outside temp, the cooler its outside, the cooler the device will be.

Any way to revert back to the stock kernel settings? I reflashed the Stock kernel for the nexus 7 but i want to know its governor and voltage and etc back to full stock settings.

if you didnt change anything, it would boot up at its default settings. or if you have set something with a cpu app to boot, unset it and reboot.

Thanks. I wanted to do a comparison of different kernels and see which fits best for my everyday usage.

depending which kernel youre using and what temp the thermal throttle is set for. you can even remove tbermal throttle when building a kernel, but the phone would just shut down when reaching the safety temp.

Nexus 7 under clocking itself

My nexus 7 keeps under clicking itself to 1.5GHz from anything.
I have stock rooted with Trinity kernel 4.2 using tkt to over clock anyone have any tips

It's called 'saving power'.
As long as it doesn't lag and clocks itself up to maximum when required, there's nothing to worry about.
Or you can get some CPU clock app and set it on maximum performance. But don't be surprised if you can boil eggs on it then and the battery dies in 2 hrs :good:

I ran my N7 at 1.7 (using Trinity) without any heating problems. Battery life was acceptable.

clear the data for tkt and reboot. if you are using tkt, you dont need a powerhal script, since tkt runs it automatically after opening it.

Does Tegra 3 really need overclocked? Having used Tegra 2 I can say that could definitely use a little bump but so far T3 is keeping up with me and I can see a big difference between T2 and T3. Makes me wonder what T4 Wayne has in store.

does it need it.. probably not. do we want to overclock anyways.. yes! btw, its underclocked by default(its rated to 1.5ghz). i use it at 1150mhz as a daily btw.

[Q] How overclock GPU?

I have nexus 7 3G 32gb with trinity kernel,stock ROM.And i have question how do i overclock GPU?

Use Trinity kernel toolbox. It has the option to set the speed of the GPU and adjust the CPU voltages

Can my GPU burn or something like that?Or high GPU frequency will cause only reboot?

I've read that the max recommended GPU speed is 484.Going much higher the battery will drain too much and will get hot. If you set the speed to high it will become unstable and usually reboot. It will reboot and rest default speeds long before it will have time to melt. Just don't use your over clock settings to be set on boot

1. easiest way, use the trinity kernel toolbox and adjust the gpu slider up or down.
2. or manually go to /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc/ with a root file explorer(like root explorer) and manually edit the variable and save it.
yes, it can get very hot if overclocking the gpu. especially when playing cpu intensive games. worst thing is youll reboot if things go haywire.

Excessive voltage and heat can easily fry a CPU/GPU and other motherboard components, so be careful.

[Q] Nexus 7 General GPU/CPU Overclocking Help?

Hey guys, I'm new to the forums and fairly new to Hacking and overclocking android devices. However I have been building and overclocking high end PC's for sometime. So I am no stranger to the risks or processes of overclocking.
But I have some questions that maybe you all can help me out with before I start overclocking my Nexus 7.
Here are my Current Specs and Software:
Nexus 7 Wi-fi version
SmoothRom v5.0 + LeanKernel
Currently I am overclocked to 1500 Mhz Max with 204 Mhz Min + Stock voltage
I have been able to find information about CPU overclocking. But after extensive searching I have not been able to find much on Nexus 7 GPU overclocking.
1. Does my kernel support GPU overclocking?
2. If so how do I enable it? Or where is it located? and what settings should I be looking for (Names)?
3. If you need an App to overclock the GPU are there any that are free (Or at least one worth paying for?).... and which one if any supports my kernel?
4. Are there any good Nexus 7 CPU and GPU overclocking guides someone could point me to?
Basically I am looking for someone who is experienced in Nexus 7 overclocking, to point me in the right direction and help me with some indepth questions that may come up.
Thanks guys

According to System tweaks App 39c to 40c while idling in that program. I don't know how accurate that app is though.... so if there is a standard better app to monitor your CPU/GPU temps I am all ears
I have yet to find an app that allows you to monitor your temps during load. Again if you can suggest one I am all for it.

Try trickstermod

Download trickster mod from the app store you should be able to change the gpu voltage there

Alright I will check that out. But what about GPU clock settings can trickster change those too??? And if so.... What setting am I looking for because I saw nothing referencing GPU clocks in those words
Sent from my Nexus 7 using xda app-developers app

It over clocks the GPU its on the 2nd to last page I think and you will see the clock speed and you can edit it, don't over kill though haha
Sent from my Nexus 7 using xda premium

Lean kernel doesn't have GPU over clocking settings. Try M-kernel, you'll find gpu settings in the specific menu of trickster mod.
